Created attachment 127568 [details] samples I've ran face detection several times on tousands of photos whith very poor results For instance, in the attached picture (1) I'd expect the algorithm to detect 6-7 faces. In the attached picture (2) I'd expect the algorithm to detect 12 faces. On my System (intel I5-3500, 16 GB, Win x64) only 3 are detected in 1 and none at all in 2. I've varied the sensivity between 0 and 100 (every ten), to no avail. I've tried all possible variations of settings in the maintenance tool as well. After the face detection is finished, there is no "unknown" tag in the left people-sidebar, but when I open the pictures in the albums view and enable "show faces tag", the mentiones 3 tags are visible. Since I mainly work on b/w pictures it might be related to that. Also, it may be same as bug 415561? STEPS TO REPRODUCE 1. Create new database 2. Create new album with attached images 3. Scan for faces
Created attachment 127572 [details] YOLO-Detection.jpg This is what the face detection would look like if we were to use a different precalculated model, see screenshot, all faces detected. The current face detection is now much better than in digiKam-6.x and earlier. But there are images where it fails. The disadvantage of the model that has the good detection is that it is much slower and the model has a file size of over 200MB. As part of the GSoC2020 we want to offer an option to download this better face model. Maik
Thanks, Mike. since accoring your explanation this an expected behaviour of the currently used model, rather than a bug, I've set the status to resolved-intentional. Cheers, Sandra
We leave the bug open until a student as part of the GSoC2020 has implemented this option to download the better model. This is a good bug report with the test images. In the other sample image in the set, also all faces are detected with the YOLO model. Maik
Hello, I have the same problem : face detection doesn't find a lot of faces and doesn't seem to recognise my already tagged ones. If i understood correctly, there will be a "model" to download which will offer better results ? Do you know when it will be available ? Thanks Thanks
Try with 7.2.0-beta1 avaialble here : https://files.kde.org/digikam/ Gilles Caulier
Hello, After upgrading to 7.2.0-beta1 and rebuilding training data, a new analyze (doesn't ignore already analyzed) doesn't seem to give better results for me : It doesn't found a lot of faces and i have none suggestions : all found faces are "Who is it ?" I tried with attachments 1 and 2 and it is like Sandra Seilmann says : "only 3 are detected in 1 and none at all in 2." : not better with 7.2.0-beta1. Thanks
What sensitivity have you set? Attempt 50-66. Note that the People view differentiates between face detection and face regonition. After the face detection, only unknown faces are found. Then you have to run the face recognition to get a suggestion. Maik
I had sensibility "80", which is the default after installing Digikam, but strangely, the "default button" set to 70. Anyway, i tried with "50", first "detect" faces then "recognize" faces : it's ok for recognizing : i have some suggestions now but there isn't more faces "detected". With attachments 1 and 2 it isn't better :"only 3 are detected in 1 and none at all in 2.". So, in all cases i have to always run first "Detect faces" then "Recognize faces" ? I usually use the contextual items actions : "Find faces". Is it similar to "Detect faces" from People view ? Do you plan to add the "Recongnize faces" to the contextual menu too ? Thanks
I run 7.2.0-beta1 on some of my images and I get very poor results on face detection. I played with the sensitivity but like Sandra and nonobio there is only a small improvement. Based on your previous comments I understand that the "new face model" is part of 7.2.0-beta1 but there is no improvement on the face detection for the sample photos of Sandra. Is the "new face model" included in 7.2.0-beta1? How do I need to configure Digikam to detect the faces as you showed in "YOLO-Detection.jpg" Honestly I don't care on a significant increase of processing time, as this task can easily run over night or for several days.

You didn't promise to much. The face detection with YOLO model works like a charm, using the sample pictures attached and my own pictures. In my point of view the improvement in detection, justifies the increase of processing time (as mentioned in ticket 42309)
Perfect with 7.2.0-beta2 and Yolo enabled. Thanks a lot :)
Just a little question i already asked here : "I usually use the contextual items actions : "Find faces". Is it similar to "Detect faces" from People view ?" If i'm right, this action from contextual menu start both "detect" and "reconize" faces ?
